T3 and T4 are considered obsolete tests and not very useful.
The "normal" ranges for FT3 and FT4 are also flawed. That's because the original population that made up "normal" had people in it with undiagnosed Hashi's and people who were hypo but not being treated.
Many of us find that we still have hypo symptoms until FT4 is midrange or a little above. The rule of thumb for FT3 is upper half to upper third of range. If you post actual results, I'll be happy to help you interpret them.
Your daughter should also have blood tests for thyroid antibodies (TPOab and TGab) to see if she has autoimmune thyroid disease (Hashi's). It's the most prevalent cause of hypo in the developed world.
There is no cure for Hashi's, just treatment. Regardless of the cause of her hypo, the only treatment is to take replacement hormones.
Being hypo is miserable...hypo is easily treatable. I wouldn't go looking for a cure since it's not out there. Many people claim to cure, but the evidence just isn't there. I think they're just taking advantage of thyroid patients.
Thanks so much for the response. Her T3, T4, free T3, free T4 are all in the normal range but skewed towards the lower limit. She has mild symptoms of weight (slightly higher), puffy face and lethargy. No others symptoms are visible.
Also I hear that Hoemeopathy has cured Thyroid problems. Any thoughts are appreciated.
That's a fairly high TSH. However, just to give you some perspective, when I was diagnosed, mine was 67, and I've hear reports of people in the hundreds.
Your daughter (?) should have free T3 and free T4 tested. These are the actual thyroid hormones (TSH is a pituitary hormone) and will give a much more complete picture of her thyroid function.
Does she have hypo symptoms?
